I am the son of a black man from Kenya and a white woman from Kansas. I was raised with the help of a white grandfather who survived a Depression to serve in Patton's Army during World War II and a white grandmother who worked on a bomber assembly line at Fort Leavenworth while he was overseas. I've gone to some of the best schools in America and lived in one of the world's poorest nations. I am married to a black American who carries within her the blood of slaves and slaveowners — an inheritance we pass on to our two precious daughters. I have brothers, sisters, nieces, nephews, uncles and cousins of every race and every hue, scattered across three continents, and for as long as I live, I will never forget that in no other country on Earth is my story even possible.

It's a story that hasn't made me the most conventional of candidates. But it is a story that has seared into my genetic makeup the idea that this nation is more than the sum of its parts — that out of many, we are truly one. -- Barack Obama in Philadelphia from the speech "A More Perfect Union"
